WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 253,152, dated January31, 1882 Application filed August 4, 188i.

To all whom it may 4concern Beit known that I, DANiELTEoMAs Bos TEL, ofBrighton, in the county` of Sussex, England, have invented certain newand use- 5 ful Improvements in Tater-Closets; and I do hereby declarethat the followingis a full and exact description thereof, referencebeing had to the accompanying drawings, making part of this application.l 1o My invention relates to that kind of waterclosets in which what areknown as side-delivery7 basins or bowls are employed, and has for itsmain objects to more edectually Hush out the bowls of this kind ofclosets, and I5 to render the apparatus more easy ot clearance in caseof any obstruction in the trap or exit-pipe, and less liable to getfouled.

To these main ends and objects my invention consists, first, in thecombination, with a 2o bowl having a side delivery and provided at itstop with a lushing-rim,of twoinlets for the supply of water to thedashing-rim, arranged so that the supply-streams enter the rim and meetat a point about opposite to that side of the bowl at which its contentsis discharged, whereby a more et'icient cleansing of the bowl anddischarge of its contents are insured, as hereinafter set forth; second,in the combination, with a side-delivery bowl, of' a tlushing- 3o rimhaving a series of discharge-apertures, in which those locatedoppositeto the side at which the bowl discharges its contents arelargest, and two inlets for the water-supply, arranged so that thesupply-streams to the tlushingrim will meet in the vicinity of thelargest discharge-apertures, all as will be hereinafter more fullyexplained; third, in a watercloset composed of a side-delivery basin anda discharge trunk or pipe which extends nearly 4o or quite up to the topof the bowl and has a removable cover, all in the manner and for thepurposes to be hereinafter more fully explained. To enable those skilledin the art to make and use my invention, I will now proceed to 4 5 morefully explain it, referringby letters ot' reference to the accompanying`drawings, which form a part of this specification, and in which- Figurelis a perspective view of the earthenware portion of a closet madeaccording to my 5o invention. Fig. 21s a top view of the same (Nomodel.) Patented in England April 11, 1877.

with the water-supply pipes attached or connected to theiushiugrim.Fig.3 is a vertical section of the same at the line m .t of' Fig. 2,showing the closet in a condition ot' disuse. Fig'. 4 is a similarsection, ilustratiug the ac- 55 tion ot' the closet when the water islet in to flush it and discharge it ot' its contents.

In the several iigures the same part will he found designated by thesame letter ot' reference.

A is the basin or bowl, formed with a side delivery at B-iu thisinstance at the rear side of the closet-and having a. flushing-rim at C.The delivery opens into a Vertical trunk or chamber, D, the top of whichis nearly or quite level with the top ot' the bowl, as shown, and thetlushingrim O has two water-supply inlets, E E.

The upper end of the trunk D is provided with a removable cover, D2, forthe purpose of 7c conveniently getting at the interior and lower par-tofsaid trunk in case ofthe collection therein of any material which mayoperate to obstruct the free discharge of' the closet, and for thepurpose of easil \v cleaningout the said trunk and the trap beneath it.it' one be used.

The two inlets E E to the flushing-rim are arranged nearly tangentiallyto the curve of the rim, project therefrom about in parallel directions,andhave connected to lhem, in the 8o usual manner of' makingconnections, the branch pipes G G, which latter, as shown, ronverge atand are connected to the lower end of the water-supply pipe F. v

The dashing-apertures ofthe rim C, as will be seen by reference to Fig.2, where a portion of the rim is broken away to show those Iapertures,are formed and arranged so that some of them-those about opposite to thevicinity of the delivery1 side of the bowl-are consider- 9o ably largerthan the rust. The object ot' this is to insure the discharge lfrom therim C of more water at those portions about opposite the delivery of thebowl, where the rushing-in supply-columns meet in the rim, and hence agreater rush of u ater from the side where theselarger apertures existtoward the delivery than in any other direction.

The entrances of the supply-columns at E E being in directions nearlytangential to the roo curve atl either side of the rim C, little or noneof the head or force of the water is dissipated by its entrance into therim, and hence the action ofthe water is very forcible.

By reference to Fig. 4 it will be observed that in the flushing anddischarge operations ofthe closet the water from the rim C not onlysweeps down over the walls of the bowl from all pants of the rim, butthat a larger supply comes from the part opposite the delivery-point B,and that therefore there is a sort of'sweeping of the contents of thebowl toward the point B bv a cataract of water, which rushes in a Sortof horseshoe-falls fashion from the top of the bowl over its walls andbottom toward its delivery side. Although the apertures of theflushing-rim are ot' greatest capacity at thelocality pointed out toeffect the purpose explained, yet the meeting of the two supplycoluinnsof water in the rim Cat the vicinity of the larger dashing-aperturescauses a superahundant water supply and pressure in this part of therim, from which a sort of backpressure arises within the rim C suticientto insure the rush of the supply-water from all parts of theflushing-rim (both the larger and smaller apertures) with nearly orquite the same force. Thus all parts of the walls of the bowl arethoroughly washed, and while a sort of vortex action occurs, at thesaine time the tendency of this action is to sweep the whole contents ofthe bowl toward the delivery or discharge B. The lower end of the trunkD communicates with the trap H, that in turn communicates with thesoilpipe connection I of the closet.

As to the general operation of the closet, it is only necessary toexplain that the watersupply to the pipe F and its branches Gr G maycome trom an overhead tank or other source and be let on and cutoff byany ofthe known and suitable means, and that after the use of the closetthe occupantcauses the water to be supplied as usual.

It will be seen that in aside-delivery closet made according to myinvention only a small quantity of water need stand in the bottom of thebowl, and that the latter may be made so shallow that not only are itssidewalls en.

tirely out of the way of catching any of the excrementtious deposits,but the latter have so short a distance to fall that no unpleasantsplashing up of the water in the bowl onto the occupant of the closetwill be experienced.

Of course many of the details of structure may be varied withoutdeparting from the gist of my invention, and one or more ofthe severaldescribed features of my invention may be used without the rest, andacloset be thus produced embodying to a certain extent the advantages ofmy invention.

Having sufficiently explained the nature of my invention to enable thoseskilled in the art to understand and practice it, what I claim as new,and desire to secure by Letters Patent,

1. In combination with the bowl of a sidedelivery closet provided with aflushing-rim, the two water-inlets E E, arranged tosupply theBushing-rim with two streams of water directed into the rim from pointsnear that opposite the frontpart of the bowl, as and for the purpose setforth.

2. In combination with a side-delivery bowl having a flushing-rim formedwith apertures largest at the point opposite the delivery side ofthebowl, and ot' diminishing capacities from said point toward the deliveryside of the bowl, the two water-inlets E E, arranged to supply theflushingrim with two streams of water directed into the rim, ashereinbefore de scribed.

3. The combination, with the side-delivery bowl having a flushing-rimand an open communication with the trap, of a trunk, D, extended upwardfrom the trap nearly or quite to the level of the top of the bowl, andprovided with a removable top, D2, all in substantially the manner andfor the purpose set forth.

In witness whereofI I have hereunto set my hand and seal this 13th dayof July, 1881.
